  * There were multiple issues with the dummy BS flag/prism gluing [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1830 |klog]]. The sapphire prisms will need to be removed and reapplied. Hirose-san is going to organize this. He wants to try the cup that had been made for the PR2 on the actual PR2 and then see if a new cup is needed for the BS (considering the different radius).
  * Hirata-san added the optical layout information to the BS Inventor assembly. He requested tank information from Mirapro so he can continue to do SR2/3/M.
  * Fabian finished the IM assembly and started on the IRM and RM. Some of the IRM panels had been improperly wrapped and really should be re-cleaned. The MPC (multi-purpose cube) on the RM will need some rework.
  * Mark scheduled a review for Thursday 6/16.		   * Mark and Fabian worked at Kamioka:
   * All the parts for the security structure were located. The clamp pieces for the IM are being taken back to Mitaka to have extra screw holes added.
   * The BS/PR2/SR2 area was cleaned and tidied to allow floor removal and assembly frame construction.
   * 21 "Type 1" cables (PI-Flange, Signal) and 15 "Type 5" cables (OSEM) were tested. They all passed. Sufficient tested "Type 2" cables (PI-Flange, Motor) were located in the PR3 area.
   * Hirata-san worked on the Inventor assembly, adding views (originally defined by Mark) of the different phases of construction.
   * Hirata-san shipped 7 SFs and some parts to Kamioka.
   * Hirata-san made assembly drawings of the damper rings and cable clamps for SR.
   * Hirata-san liaised with Mirapro about the frame assembly.

   * Akutsu-san is working to get wide-mouth OSEMs
  * Longer cables for BF->PI and SF->PI.
   * Takahashi-san has ordered extra connectors (due any day) and will get a company to make the cables.
